efforts to increase the mass transfer coefficient, enhance the contact area, and decrease the power input of contractors have given risen to the development of the pre-dispersed solvent extraction (pdse) contactor and the devise of the new dissolved nitrogen pdse (dnpdse) contactors. the studies conducted after the design of the new contactor to determine the working conditions for its suitable...

The paper focuses on the design of wire harness assemblies for mass customization by a delayed product differentiation. In order to manufacture wide diversified products, two algorithms are proposed both using a generic representation of wire harness with all options and variants in order to produce each wire harness in a short period of time. An industrial case study is presented in a contract...

This Case describes two similar outsourced IS projects that took place in Wellington, New Zealand (NZ) during the period 1992-99, with emphasis on the reasons why one project failed (the prime contractor repudiated the contract and the project was abandoned) and why the other succeeded. The same prime contractor was used for both projects and there were a number of other similarities, yet the o...

Developing a system design for government projects typically requires a defense contractor to evaluate and make system decisions based on documents such as a request for proposal (RFP), statement of work (SOW), and concept of operations (CONOP) as shown in Figure 1. From these documents, a contractor must assess system alternatives while maximizing the customer’s expected system goals, objectiv...

The Commission, supported by a contractor, has been working with the Member States and stakeholders regarding the development of the strategic framework referred to in Action 6a. During the period October 2012 to end 2013 there have been 4 meetings of a dedicated working group. In addition, a workshop was held on 29/30 May 2013 in Brussels.

This study examines the causes of time delays and cost overruns in a selection thirty post-disaster reconstruction projects Iraq. Although delay factors have been studied many countries contexts, little data exists from under conditions characterizing Iraq during last 10-15 years. A case approach was used, with construction different types sizes selected Baghdad region. Project gathered survey ...

This paper describes the practical experiences of the authors subsequent to the 1993 Symposium and overlays the procurement process that took place for the development of the first tranche of the Royal Air Force’s Logistics Information Technology System from a COMPUSEC perspective. It explains some of the problems encountered by the Security Team during the selection of a Prime Systems Integrat...

A set of tools was developed in the frame of ESA activity [18191/04/NL] labelled RCET (Mars Rover Chassis Evaluation Tools) to support design, selection and optimisation of space exploration rovers. This activity was carried out jointly by Contraves Space as prime contractor, ETHZ, DLR, SSC and EADS Space Transportation. This paper describes the utilisation of the RCET in the context of a rover...

The concept of construction supply chain (CSC) is defined firstly. Then the authors depict a typical construction supply chain model from the perspectives of partners involved in construction process, analyze the characteristics and attributes of CSC, and identify some problems in CSC. Based-on the definition and principles of supply chain management (SCM), the concept of construction supply ch...
